Answer: the cube root of 512 is 8.
Step-by-step explanation:
First divide 512 and take the least factors as I have shown,
512= 2×2×2×2×2×2×2×2×2
Now, make the triple twins of these factors,
(2×2×2)(2×2×2)(2×2×2)
Now, take one number from each pair and multiply them,
2×2×2=8
Therefore, the answer of the cube root of 512 is 8.
Since you have to distribute both numbers, you'll end up with x^2-3x+4x-12 then simplify and it is x^2+x-12
Where is X in the equation?
Answer:
x=9, y=-4. (9, -4).
Step-by-step explanation:
2x+5y=-2
4x+7y=8
--------------
-2(2x+5y)=-2(-2)
4x+7y=8
---------------------
-4x-10y=4
4x+7y=8
--------------
-3y=12
y=12/-3
y=-4
2x+5(-4)=-2
2x-20=-2
2x=-2+20
2x=18
x=18/2
x=9
Answer:
She need to sell 7 or more plants to make the commission offer the best paying option
Step-by-step explanation:
Given : Jill has a job offer. She is offered either $50 per day or ?30 per day plus a commission of $3 for every plant she sells.
To Find: How many plants does she need to sell to make the commission offer the best paying option?
Solution :
Since in the commission offer
She earns $ 30 per day and $3 for each plant she sells
Let she sold t plants
Since commission of 1 plant is $3
So, commission of t plants is $3t
And She is also getting $30 per day
So, total amount earned in the commission offer is 30+3t
Since we need to find How many plants does she need to sell to make the commission offer the best paying option
So, 30+3t > 50
⇒
⇒
⇒
⇒
Thus she must sell 7 or more plants
Hence she need to sell 7 or more plants to make the commission offer the best paying option
